Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657950, here are decompositions:

17 + 8657933 = 8657950
23 + 8657927 = 8657950
47 + 8657903 = 8657950
101 + 8657849 = 8657950
149 + 8657801 = 8657950
167 + 8657783 = 8657950
179 + 8657771 = 8657950
227 + 8657723 = 8657950

Showing the first eight; more decompositions exist.
